Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
419 PM EDT Tue Jun 18 2024

.SYNOPSIS...Strong surface high pressure centered off the New
England coast working in tandem with falling pressures over the
Yucatan Peninsula and the Bay of Campeche is expected to result in
moderate to fresh breezes tonight through late week. An area of
low pressure may develop mid week a few hundred miles north of the
central Bahamas towards mid week and move towards the Southeast
coast. This may result in a slackening of breezes, but confidence
is decreasing in the development of this system.
